DANGER: RISK OF ELECTROCUTION
WARNING
All field wiring and components MUST be installed by a licensed electrician and
MUST comply with the applicable legislation.
WARNING
If NOT factory installed, a main switch or other means for disconnection, having a
contact separation in all poles providing full disconnection under overvoltage
category III condition, MUST be installed in the fixed wiring.
WARNING
▪
ONLY use copper wires.
▪
Make sure the field wiring complies with the applicable legislation.
▪
All field wiring MUST be performed in accordance with the wiring diagram
supplied with the product.
▪
NEVER squeeze bundled cables and make sure they do NOT come in contact with
the piping and sharp edges. Make sure no external pressure is applied to the
terminal connections.
▪
Make sure to install earth wiring. Do NOT earth the unit to a utility pipe, surge
absorber, or telephone earth. Incomplete earth may cause electrical shock.
▪
Make sure to use a dedicated power circuit. NEVER use a power supply shared by
another appliance.
▪
Make sure to install the required fuses or circuit breakers.
▪
Make sure to install an earth leakage protector. Failure to do so may cause
electric shock or fire.
▪
When installing the earth leakage protector, make sure it is compatible with the
inverter (resistant to high frequency electric noise) to avoid unnecessary opening
of the earth leakage protector.
Install power cables at least 1 m away from televisions or radios to prevent
interference. Depending on the radio waves, a distance of 1 m may not be
sufficient.
WARNING
▪
After finishing the electrical work, confirm that each electrical component and
terminal inside the electrical components box is connected securely.
▪
Make sure all covers are closed before starting up the unit.
NOTICE
Do NOT operate the unit until the refrigerant piping is complete. Running the unit
before the piping is ready will break the compressor.
NOTICE
If the power supply has a missing or wrong N-phase, equipment will break down.
